Chain Links, of which the following is a specification.

rl`he present invention relates to interlocking chain-links; and its object is to provide such links which may bereadily intel-locked or connected and readily disconnected or unlocked as may be desired, and which will,

when interlocked, be securely held against accidental unlocking. y

rllhis object is attained by, and the inven tion finds preferable `embodiment in, the chain-link structure hereinafter described and illustrated bythe accompanying drawing, in which Figure l is a plan view of a chain showing my interlocking links;

Figure 2 is a side view thereof; Y

Figure 3 is a transverse sectional view of one orP the interlocking links taken on line 3-3 of Figures l and 2;

Figure d is a side view ot the interlocking links, illustrating their interrelative positions at the beginning of the operation of interlocking the saine;

Figure 5 is a similar view illustrating said links in other and subsequent positions of said operation;

Figure 6 is a side view of the rst interlocking link; and

Figure 7 is a side view of the other (the second) interlocking link and a portion of a connected ordinary chain-link` My first interlocking link l has opposite sides 2, spaced apart and connected at one end ot the link by the bight portion 3, and has also a tongue 4f, This tongue is carried bythe middle part of the bight portion 3 and extends as particularly showninFig ures l and 3) in planes which are spaced inwardly from the sides 2, so that a clearance space isprovided between the tongue Vand the sides 2 cn either side ot the tongue.

The tongue thus desirably extends (as particularly shown in Figures 2, 4:, 5 and 6) first in the longitudinal direction of the link outwardly at 6 from the bight portion and then extends in bowed forni, as seen at 7, outwardly from the sides 2, and then approaching said sides, to its point or eX serial no. 5eme/i.

treinity 8 which is desirably between said sides 2 The second interlocking link 9 has opposite sides l() which are parallelly shaped (as particularly shown in Figures 2, il, 5 and 7) such sides 1G being connected bybight portions 11, l2.

ln the operation ot interiockingthe links l and 9, the bight portion l2 et the secondi7 link 9 is inserted between the sides 2 ot the first ink l (as seen in dotted lines at in Figure d), and the bight portion ll et the second link 9 is swung (as seen in solid lines in Figure l) between the sides E and hooked over or passed around the point er extremity 8 of the first links tongue d, and is then moved along the tongue in a turning inovenient (successive positions thereof being seen in dotted lines B, C and solid lines l) in Figure 5) and is then turned reversely to connected or interlocked position with the first link 1 (seen in Figures l and 2), in which position the bight por tion 3 ot the lirst link l engages both sic es l0 of the second link 9. ylliese movements, ot course, are reversed in disconnecting or unlocking the links l and 9.

it will be seen that these interlocking links are securely held against accidental unlocking. My invention may be applied to various uses; as instance, the cross chains in anti-skidding"7 chains used on automobile tires.

l. ln a device of the character described; a lirst link having spaced opposite sides,

bight portion connecting the sides, and

tongue carried `by the bight portion and extending in planes spaced inwardly from. the sides and having a middle portion bowed outwardly :trom the sides; and a second link having spaced opposite sides parallelly lilshaped, and bight portions connecting the sides, and being adapted to be inserted between the sides of the first link and passed around the point of its tongue and along the tongue to a position in which the bight portion of the rst link engages both sides of the second link.

2. ln a device of the character described;

a irst link having spaced opposite sides,

a bight portion connecting the sides, and tongue carried by the bight portion and eX- tending in pla-nes spaced inwardly from the sides, first in the longitudinal direction of the link outwardly from the bight portion,
